UNITE/,D STATES PATENT Friso,

DANIEL N. BAXTER, OF ROODHOUSE, ILLINOIS, ASSIGNOR OF ONE-HALF TO DAVID F. KING, OF SAME PLACE.

Boden-CLEANER.

SPECIFICATION forming part of Letters Patent 170.370,30, dated September 20,1887.

(No model.)

To @ZZ whom t may concerm Beit known that I, DANIEL N. BAXTER, a citizen of the United States, residing at Roodhouse, in the county of Greene and State of Illinois, have invented certain new and useful Improvements in Boiler-Cleaners; and I do declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and iigures of reference marked thereon, which form a part of this specification.

This improvement relates to provisions for purifying the water of steam-boilers, and for catching and collecting sediment which may be blown off from time to time.

The improvement consists, chieiiy, of two vessels or drums located at different levels. The upper vessel is the settlingdrum and the lower vessel is a combined cooling and sediment drum. The two drums are connected by a pipe which has a globe-valve. The upper drum is connected at its top with the steamdome of the boiler and ata sh ort distance from its top with the boiler at or about the waterline, and the lower drum communicates with the bottom of the boiler at a short distance from its top, and is provided with a `blow-ofi' pipe.

The novelty consists in the peculiar construction and combination of the parts, which will be more fully hereinafter set forth,claimed, and shown in the annexed drawings, in Which- Figure 1 is a perspective View of a boiler embodying my invention, and Fig. 2 a diagrammatical view showing the relative arrangement of the parts.

The boiler A may be of any approved pattern, and the settlingdrum Bis located opposite thereto, so that its top is below the top of the boiler, and is connected with the steamdome C by the pipe E,which has a globe-valve, e, for opening or closing said pipe for admitting live steam to the drum for cleaning it, or for shutting the steam off therefrom when required. The pipe J, interposed between and connected at one end with the drum at ashort distance from its top and at the other end with th e boilerat or about the water-line, is provided vided with the globe-valve g, and the pipe H 6o connects it at a short distance below the top with the bottom of the boiler,and is provided with the globe-valve h. The lower end,which extends some distance below the bottom of the boiler, has the blow-off pipe I extended therefrom, which is opened and closed by the globe-valve i.

In practice the scum and foreign matter rising to the top of the water when ebullition takes place passes off through'pipe J into the 7C settling-drum, arid the clear water will pass from this drum into the sediment-drum, and from thence into the boiler. To clean out the settling-drum, the valve g is closed and the valves e and f are opened, and the steam en- 7 5 tering the drum will force the scum and foreign matter out through the spout F. The heavier particles of sediment-such as sand, Stewill pass from the boiler into the sedimentdrum through the pipe H, and from the drum B So through the pipe G, Where it will collect, and from which it can be blown out at intervals by live steam from the boiler by opening the valves e, g, and i.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. rIhe combination, with the boiler, of the two drums located at different levels and communicating with each other and with the boiler 9c at points corresponding with the steam-space, the water-line, and water-space, substantially as and for the purposes described.

2. The combination, with the boiler and the two drums located at different levels, of the pipes connecting the top of the settling-drum with the steam-space of the boiler, the pipe leading from the water-line of the boiler and communicating with the settling-drum at a short distance from its top, the pipe conncct- 10o The lower end is funnel- 55 ing the two drums, the pipe connecting the ment-drum, the pipe G, having a globe-valvelower drum with the bottom of the boiler, the and connecting the two drums, the pipe H, blow-off pipe, and the globe-valves located in having the'globe-valve h,connecting the sedir 5 each of the several pipes, substantial] y as and ment-drum with the bottom of the boiler, and 5 for the purposes described. the blow-off pipe I, having the valve ,substan- 3.
